Function Description
Core Function of Key Product Categories
Each product category is designed to perform specific critical functions, directly impacting equipment performance, safety, and longevity. All functions are aligned with OE standards, ensuring compatibility and optimal performance:
• Pump Assemblies: Convert mechanical energy into hydraulic or fluid energy, delivering consistent flow and pressure for drilling fluid circulation, lubrication, and spray systems. The AH1602011200 Spray Pump Assembly, for example, provides a flow rate of 15-25 L/min (depending on operating pressure) to ensure uniform spray distribution, while the P25×378BEIU257 Main Oil Pump maintains stable lubrication for engine and transmission components.
• Connection & Line Assemblies: Facilitate secure, leak-free transfer of fluids (oil, water, drilling mud) and air between equipment components. The DW40C0701wg38000015 Quick-release Connection allows for tool-free disassembly in 30 seconds or less, reducing maintenance time, while the ZJ70DB BK-Z2 High-pressure Hose withstands operating pressures up to 40MPa, ensuring durability in harsh drilling environments.
• Filters & Seals: Remove contaminants (particles, debris, moisture) from fluids to protect internal components (pumps, valves, bearings) from abrasion and corrosion. The P556916 Filter Element has a filtration accuracy of 10 microns, capturing 99.8% of particles larger than 10μm, while the 5P5846 Seal provides a compression set of ≤15% (per ASTM D395) for long-term leak prevention.
• Bearings & Bushings: Reduce friction coefficient to ≤0.005 (for steel-on-steel contact) between rotating or sliding parts, minimizing wear and energy loss. The 430129140061177016 Crosshead Bearing has a dynamic load rating of 220 kN, supporting high axial and radial loads in drilling rig crossheads.
• Valves & Relays: Regulate fluid flow direction, pressure, and volume, and ensure electrical safety in control systems. The MFH-3-1/4 Solenoid Valve has a response time of ≤50ms, enabling precise control of hydraulic circuits, while the PHOENIX Safety Relay provides 24V DC operation with 8 normally open and 1 normally closed contacts, ensuring compliance with IEC 61508 safety standards.
Structural Features
Design Advantages for Industrial Durability
Our mechanical parts are designed with structural features that prioritize durability, compatibility, and ease of maintenance—addressing the unique challenges of heavy industrial and drilling environments (high pressure, high temperature, dust, vibration):
• Material Selection: All parts use high-grade materials tailored to their application: carbon steel (for sprockets and shafts) with a hardness of HRC 45-50, stainless steel (for valves and filters) to resist corrosion, nitrile rubber (for O-rings) with a shore A hardness of 70-80, and bearing steel (GCr15) for high wear resistance.
• Precision Manufacturing: CNC machining with a tolerance of ±0.01mm ensures perfect fit with OE equipment, eliminating compatibility issues. For example, the JC28/11D-06-16 Shaft Sleeve has an inner diameter tolerance of ±0.005mm, ensuring seamless integration with rotating shafts.
• Sealing & Protection: Double-seal design for valves and pumps prevents fluid leakage, while anti-corrosion coatings (zinc plating, powder coating) extend service life in harsh environments. The 5303100550 Main Shaft O-ring (515×7) features a rounded cross-section for improved sealing under high pressure.
• Modular Design: Many parts (e.g., repair kits, quick-release connections) feature a modular design, allowing for easy disassembly and replacement without specialized tools. The 2097290 Repair Kit includes all necessary seals and gaskets for one-time maintenance, reducing downtime.
• Load-bearing Capacity: Structural reinforcement for high-load components—such as the 430129140061177016 Crosshead Bearing and JC70B Sprocket—ensures they can withstand the extreme forces of drilling operations (up to 500 kN for crosshead bearings).
Applicable Working Conditions
Our mechanical parts are engineered to perform reliably in the most demanding industrial and drilling environments, with specific compatibility for the following working conditions:
• Drilling Rigs (ZJ30C, ZJ50D, ZJ70D, ZJ70DB, JC70B): Suitable for onshore and offshore drilling operations, withstanding operating temperatures of -40°C to 120°C, operating pressures up to 100MPa, and high vibration (≤5g). Ideal for oil and gas drilling, geothermal drilling, and mineral exploration.
• Qiandele 8240 Pressurized/Supercharged Thickeners: Designed for industrial slurry processing, compatible with working pressures of 0.6-1.2MPa and temperatures of 0°C to 80°C, resistant to slurry corrosion and abrasion.
• Mud Pump Groups (ZJ-30C): Suitable for heavy-duty mud circulation systems, withstanding high viscosity fluids (up to 1000 cP) and continuous operation for 24/7 drilling cycles.
• General Industrial Equipment: Applicable to boiler systems (WNS0.5-0.8-Y/Q), hydraulic systems, and power generation equipment, operating in environments with dust, humidity, and variable temperatures (-20°C to 100°C).
All parts comply with international standards (ISO 9001, API 7K for drilling components) to ensure performance and safety in these harsh conditions.
Maintenance & Care Recommendations
Proper maintenance of mechanical parts is critical to extending their service life and ensuring equipment reliability. Below are practical, easy-to-follow maintenance recommendations based on industry best practices:
• Regular Inspection: Inspect filters, seals, and hoses every 500 operating hours; replace filter elements (P556916, 1421403) every 1000 operating hours or when pressure drop exceeds 0.5MPa. Check O-rings (P-1848, 5303100550) for cracks or deformation every 800 operating hours.
• Lubrication: Apply high-temperature lithium grease (NLGI Grade 2) to bearings (430129140061177016) and bushings (4N6658) every 300 operating hours. Ensure lubrication coverage of 100% of the contact surface to reduce friction.
• Cleaning: Clean quick-release connections (DW40C0701wg38000015) and valve ports with a non-corrosive cleaner before installation to prevent contamination. Remove debris from sprockets (7001050241) and shafts to avoid wear.
• Storage: Store parts in a dry, clean environment with a temperature range of -10°C to 40°C. Avoid direct sunlight and contact with corrosive substances (oil, chemicals). O-rings should be stored in sealed containers to prevent oxidation.
• Replacement Guidelines: Replace parts when they show signs of wear (e.g., bearing noise, seal leakage, filter clogging) or reach their recommended service life (e.g., 5000 operating hours for pumps, 3000 operating hours for hoses). Use only compatible replacement parts to avoid equipment damage.

On-site Fault Repair Cases
Below are three real-world on-site fault repair cases, demonstrating how our parts solve common equipment issues and reduce downtime:
Case 1: Drilling Rig Hydraulic System Leakage
Equipment: ZJ70D Drilling Rig
Fault: Hydraulic oil leakage from the oil return line, causing a 20% drop in system pressure and unplanned downtime.
Root Cause: Worn O-ring (P-1848) in the DQ70BSD 9722120013 Oil Return Line Assembly, due to 2500 hours of continuous operation.
Solution: Replaced the worn O-ring with our P-1848 O-ring (compliant with ASTM D2000 standards).
Result: Leakage stopped immediately, system pressure restored to 35MPa (normal range), and the rig resumed operation within 1 hour. The new O-ring has maintained a leak-free performance for over 1200 operating hours.
Case 2: Qiandele 8240 Thickener Slurry Cup Malfunction
Equipment: Qiandele 8240 Supercharged Thickener
Fault: Slurry cup failed to rotate, causing slurry accumulation and reduced thickening efficiency.
Root Cause: Damaged slurry cup shaft drive block (07-0045) due to abrasion from hard particles in the slurry.
Solution: Replaced the drive block with our 07-0045 Slurry Cup Shaft Drive Block (made of high-wear-resistant steel).
Result: Slurry cup rotation restored, thickening efficiency improved by 15%, and the drive block has withstood 1800 hours of operation without wear.
Case 3: JC70B Drawworks Sprocket Wear
Equipment: JC70B Drawworks
Fault: Sprocket (Z=98, P=508) tooth wear caused chain slippage, risking hoisting safety.
Root Cause: Original sprocket material insufficiently hardened, leading to tooth wear after 3000 operating hours.
Solution: Replaced with our 7001050241 Sprocket (HRC 48-52 hardness, CNC-machined teeth).
Result: Chain slippage eliminated, hoisting safety restored, and the sprocket is expected to last 5000+ operating hours (67% longer than the original part).
